Respuesta :
identical because the moon changes it’s look everyday but in the same order every month so if they kept keeping data then they would have a consistent pattern and what they’re doing right now is testing how the moon looks different so it wouldn’t be “non-testable” and it probably wouldn’t be complex because it’s pretty easy to keep data and draw and describe the moon every night so no hard work needed. that’s why i think the right answer is “identical”
